101 Then Samuel took the bottle of oil, and put the oil on his head and gave him a kiss and said, Is not the Lord with the holy oil making you ruler over Israel, his people? and you will have authority over the people of the Lord, and you will make them safe from the hands of their attackers round about them, and this will be the sign for you: 2 When you have gone away from me today, you will see two men by the resting-place of Rachel's body, in the land of Benjamin at Zelzah; and they will say to you, The asses which you went in search of have come back, and now your father, caring no longer for the asses, is troubled about you, saying, What am I to do about my son? 3 Then you are to go on from there, and when you come to the oak-tree of Tabor, you will see three men going up to God to Beth-el, one having with him three young goats and another three cakes of bread and another a skin full of wine:

Commentary on 1 Samuel 10:1-8

(Read 1 Samuel 10:1-8)

The sacred anointing, then used, pointed at the great Messiah, or Anointed One, the King of the church, and High Priest of our profession, who was anointed with the oil of the Spirit, not by measure, but without measure, and above all the priests and princes of the Jewish church. For Saul's further satisfaction, Samuel gives him some signs which should come to pass the same day. The first place he directs him to, was the sepulchre of one of his ancestors; there he must be reminded of his own mortality, and now that he had a crown before him, must think of his grave, in which all his honour would be laid in the dust. From the time of Samuel there appears to have been schools, or places where pious young men were brought up in the knowledge of Divine things. Saul should find himself strongly moved to join with them, and should be turned into another man from what he had been. The Spirit of God changes men, wonderfully transforms them. Saul, by praising God in the communion of saints, became another man, but it may be questioned if he became a new man.
